JACOB C. JOBGENSEN, OE BEVERLY, MASSACHUSETTS, ASSIGNOR TO 'UN-lITED' SHOE MACHINERY CORPORATION', OF PATERSON, NEW JERSEY, A CORPORATION 0F NEW JERSEY MACHINE FOR NSERTING- FASTENINGS Application filed March 27, 1,931. Serial N0. 525,818.

This invention relates to machines including in their' organization means for insertingor driving fastenings, and is herein disclosed as applied to a heel-seat lasting machine lof the type illustrated in Letters `Patent No. 1,852,015, granted upon an application of min-e on April .5, 19.32. It is to be understood, however, that the invention is not limited to machines of that particular type nor to machines for lasting shoes.

Machines of the type disclosed in the above-mentioned Letters Patent have an automatically determined cycle of operations to wipe the heel end of the upper into lasted position and to drive a gang of tacks to fasten the upper. It is sometimes desirable to run suoli a machine through its cycle a plurality of times without any work in the machine, in order, for example, to assist `by use of the tack drivers in dislodging some obstruction that may interfere with the closing movement of one or more of the tackholding lingers. The present invention provides novel controlling mechanism whereby the feeding of tacks may be prevented when the machine is used in this manner, thus avoiding undue waste of tacks. The invention is illustrated as embodied in a modification of controlling mechanism heretofore provided'in machines of the above-mentioned type for preventing both the feeding of tacks and the operation of the driving means when it is desired to wipe the upper over the insole a greater number of times than provided for by a single cycle of operations, the construction shown comprising a device movable either into position to prev-ent the feeding of tacks and the operation of the driving means, as heretofore, or into position to prevent the feeding of tacks without interfering with the operation of the driving means. This enables the operator readily to control the machine in suchmanner as to produce either of the desired results.

The novel features of the invention will now be more particularly described by reference to the accompanying drawings and thereafter point-ed out in the claims.

mechanism.

Machines of the type illustrated in the above-mentioned Letters Patent include in their organization wipers 10 for wiping the marginof the 'heel end of an upper over an insole on a last, each wiperhaving thereon a group of tackers for driving tacks to fasten the upper' to the insole. The tackers com'- prise spring-controlled fingers 12 which cooperate withyflanges lton' the wipers to provide tack pocket-s` for holding the tacks in position to be driven, andl drivers 16 for driving the tacks, the group of drivers associated with veach wiper being secured to [an operating `block or head 18 having a stud '20 mounted in a slot (not shown) in an-operating member 22 so'that the wipers and ,the blocks 18 may move in `a horizontal plane relatively to the member 22. The member 22 is connectedby a linkQt to a vertically movvie'w illustrating more clearly certain details of the controllingl able driver-operating head 26 which iS COnnected Iby ,a link 28 to a pivotally mounted lever 30. The lever 30 is controlled by a cam 32 .on a power-driven camshaft ,34 by which i the `wipers and other parts of the ymachine also are operated, this cam actingon a piling- `er 36 to lift the lever 80 against ,the vresistto a complete revolution of the cam shaft 34 and that the machine comes automatically toa stop at the end of the cycle.

At the proper time in the cycle also tacks are fed to the tack pockets under the drivers l-through fieXible tubes which receive the tacks from a separator 42 movable across the lower ends of a plurality of inclined race- -ways formed in aV raceway block 44. The tacks are supplied to the raceways by an oscillatory tack hopper 46 fast on a rock shaft 48 which is operated yieldingly through a rack bar 50 and a spring 52 by a cam (not shown) on the cam shaft 34. It will be understood that in each cycle of the machine the rock shaft and hopper are movediirst in one direction and thenin the reverse direction. The separator 42 also is operated by the rock shaft 48 through connections not herein shown in detail but including an inclined-rock shaft 54 operated through a universal joint by the shaftv 48 and connected by gearing to another shaft 56 which has a yielding connection with a slide 58 on which the separator is mounted. For amore com` plete understanding of details of theytackfeeding mechanism reference mayl be made to Letters Patent No. 1,129,881, granted on March 2, '1915 upon application of R. F. McFeely. The tacks are fed to the tack pockets near the end of each cycle, ready to be` driveninto La shoe operated upon by the machine in the `next cycle. y f Machines of the illustrated type have been provided heretofore with controlling mechanism whereby both the feeding of tacks and the operation of the driving means may be prevented during the cycle of the machine,

so that the upper may, when desired, be vwiped inwardly over the insole a greater ,number of'timejs before it is fastened then provided -for'by a single cycle of operations. This mechanism comprises a lever 60 fast on arock shaft V62 mounted on the head of the. machine, the upper armv of this lever'being -movable into position to engage a lug 64 on the tack `hopper 46 and thus to prevent the rock shaft'48 from moving far enough, under the influence of the yieldingly operated rack ybar 50, to cause the separator 42 to separate tacks from'the raceways. The lower armv of the, lever 60 has a pin-and-slot connection with a forked slide 66A which is movable into Vposition to embrace the plunger 36 under shoulders 68 on the plunger and thus to prevent such downward movement of the lever v3Q as to operate the tack drivers 16 when the upper karmof the lever 60 is in position to ,prevent the feeding of tacks. For moving the lever 60 into positionthus to prevent the `feeding of `tacks and the operation of the drivers o r into position to permit these operations asa part of the normal cycle of the machine, there is fast on vthe rock shaft 62 a vhand lever 70.

type it may sometimes be desired to run the machine through its cycle a plurality of times without any work in the machine, in order, for example, to assist by use of the tack drivers 16 in dislodging some obstruction that may interfere with the closing -movement of one or more of the tack fingers 12. For purposes of the present invent-ion the abovedescribed controlling mechanism is so constructed that in one position, while permitting such operation of the drivers, it will prevent the feeding of tacks, so as to avoid undue waste of tacks as well as annoyances due to the discharge of large numbers of tacks. This position of the mechanism is illustrated in Fig. 3, 'where it will be observed that the 'slide (i6-is withdrawn from under the shoulders 68, but that the upper arm of the lever 60 is in position to engage the 4lug 64 ony the tack hopper and thus to prevent the feeding of'tacks. Alternatively the ccntrolling mechanism may be positioned as illustrated in Figs.` 1 and 2 to prevent both the feeding` of tacks and the operation Vof the drivers,` as heretofore, or may be moved to a position in which the lever `60is out of the path of movement of the lug 64 and the slide 66 withdrawn from under the shoulders 68,

lmachine may be run lthrough its cycle any desired numberof times without the feeding of tacks to the tack pockets. lt will be evident,`ho\vever,:that in the first cycle of the machine under these conditions tacks fed to the tack pockets at the end of the previous cycle will be discharged, and that before resuming normal use of the' machine on a shoe it will be necessary to run the machine through at least one cycle with the illustrated controlling mechanism in its normal. position, in order tosupply the tack pockets withtacks to be used in the shoe. While the invention is illustrated as applied toa machine which utilizes tacks, it will be understood that it is not limited to the use of fastenings of that particular kind; and it will also be understood that the invention is not limited as to the number of fastenings ldriven in the cycle of the machine.
